LAPTOP Hotspot?

The link in the previous reply has to do with using a Linksys Router.

Still looking for the actual answer to the original question.

...okay. I haven't done this for years, and it was with Slackware, but you'll need a wifi card that will go into "master" mode, hostapd, and probably to set up a bridge interface or do some iptables forwarding tricks.

For the first, run lspci and look for your wireless adapter's chipset number, and then go here:

...and see if there's a "yes" in the AP column. If not, you need a new wifi adapter.

After that, I'd look at this page. It's for Arch, but the basics will be the same for Ubuntu.

From there everything should Just Work(tm).

Try this, it is for debian but should work with Ubuntu, too:

Funnily enough, I'm potentially going to want to do something along these lines with a Red Hat/CentOS/Scientific* laptop...

*Depending on what I choose to go with.

Use hostapd.
fisrt you need to put your eth0 to bridge
brctl addbr br0
ifconfig eth0
brctl addif br0 eth0
in hostapd you need to have line (preferably somewhere very close to top):
and then
hostapd -B /path/to/config/file/for/hostapd
then wait few seconds
dhclient -v br0
No iptables, arptables, ebtables needed. It is just working
